i'm using 3D-Coat for a few years now, but every once in a while (more often then i'd like) the smart materials won't work.
they're all distorted and striped and smeared in the preview, and the actual result after applying is nowhere like it should be, and completely different from the preview too.
If i keep exporting my mesh from Maya or 3DSMax as Obj with lock normals set, sometimes it fixes itself, but mostly, once it does that, there is no getting it right, whatever i do.
In the past i sometimes could get it fixed by throwing away all layers except layer 0 and start adding layers again, but often it doesnt either.
I use the Demo version, i'd like to buy the full version, but since it has been so glitchy for years it's not worth the money for me, i'm not rich, so if i save my money for something like this, it needs to work flawlesly, infact, i have been thinking about switching to Substance painter cause it never glitches on me, it's just a little less user friendly, that why i keep trying 3D-Coat.
This is what i mean (attachment) , why does it do this, and how can i fix it when it happens ?
